Aabstract public function myMethod();

Bpublic function myMethod() {}

Cfunction abstract myMethod();

In PHP, abstract methods are declared with the keyword abstract before the function signature and have no body (no curly braces).
Step 2: Check each option
abstract public function myMethod(); correctly declares an abstract method: abstract public function myMethod();. Options B and D have bodies or wrong order, and C uses incorrect syntax.
Final Answer:
abstract public function myMethod(); -> Option A
Quick Check:
Abstract method = abstract + no body [OK]
